Abstract
Programmed cell death (PCD) is a fundamental genetically controlled process in most organisms. PCD is responsible for the selective elimination of damaged or unwanted cells and organs to maintain cellular homeostasis during the organ’s development under normal conditions as well as during defense or adaptation to stressful conditions. PCD pathways have been extensively studied in animals. In plants, studies focusing on understanding the pathways of PCD have advanced significantly. However, the knowledge about the molecular basis of PCD is still very limited. Some PCD pathways that have been discovered in animals are not present in plants or found with a similar form. PCD in plants is developmentally controlled (by endogenous factors) to function in organs development and differentiation as well as environmentally induced (by exogenous stimuli) to help the plant in surviving under stress conditions. Here, we present a review of the role of PCD in plant development and explore different examples of stress-induced PCD as well as highlight the main differences between the plant and animal PCD.
Keywords: Autophagy, apoptosis, ferroptosis, hypersensitive response, programmed cell death, reactive oxygen species, vacuolar cell death, stress.

Nutrition and Metabolism in Musculoskeletal Diseases
The musculoskeletal system consists mainly of cartilage, bone, muscles, tendons, connective tissue and ligaments. Balanced metabolism is of vital importance for the homeostasis of the musculoskeletal system. A series of musculoskeletal diseases (for example, sarcopenia, osteoporosis) are resulted from the dysregulated metabolism of the musculoskeletal system. Furthermore, metabolic diseases (such ...read more
Protein Folding, Aggregation and Liquid-Liquid Phase Separation
Protein folding, misfolding and aggregation remain one of the main problems of interdisciplinary science not only because many questions are still open, but also because they are important from the point of view of practical application. Protein aggregation and formation of fibrillar structures, for example, is a hallmark of a ...read more
